I can't recall the article, I suspect it was Arstechnica, but new batteries should be kept between 20-80%. And most chargers and battery controllers are smart enough to manage it.

The only time when a battery need to be run down is when the controller gets confused and states e.g. 99% charged and never reach 100%.

And a quick snapshot hint: Mine and Zoid's pics have a drop shadow. When taking a screen snapshot, we all know Cmd-Sh-3 gives screen and Cmd-Sh-4 gives crosshair for selection. Now try Cmd-Sh-4 then press space. The crosshair changes to a camera to take the entire active window you click on on, with a drop shadow (which can be removed in system tweaks like tinker tool)

Edit: PS Rishalin - for that, I hate you

Late 2011 MacBook Pro, purchased as refurbished stock in March 2012. It's always plugged in when I'm at my desk, but I quite often use it on the train while commuting, in meetings, in the lounge while watching TV, running off battery, so it gets drained quite often.

Nice tip there GreGorGy. Thanks.

Koffiejunkie. Your stats have me thinking of trying out CoconutBattery (instead of BatteryHealth). My kingdom for a placebo.

Did a recalibration yesterday - and lost 2%. Friggin ridonkulous. Hoping to stop obsessing about this soon but GEEZ it grinds me that I have a *pap* battery....

I haven't seen a setting for something like that. If there isn't you'd need to keep connecting and disconnecting the power. You'd also want to keep it around the optimum storage charge rather than discharging from 80% down to 20% then recharging.

You just made me feel slightly better. That looks more "real-world" to me. :cool:

When I'm running off battery it's always being hammered. Card readers, external drives and full screen brightness. I guess it takes it's toll after a while.

Oh well... :wtf:

MyBB_Battery Status.png

Will run it down flat, and then charge it up to full capacity again, to see if that helps.
Silly question(?) -- can I work on it whilst it's charging after the run-down, or must I simply leave it closed to finish the charge?

A bit of googling, and getting the original part from the US, together with postage, is going to work out more expensive than having DigiCape/Core do it this side...

Hopefully the recalibration will get things sorted... Put it in sleep mode, and left it for a week or so - when I fired it up, it wouldn't switch on without the mains plugged in. The week before, things were fine, with it hanging around 83% - and status being reported as "OK"... So something happened that the battery didn't like while it was sleeping.. :whistling:

Why sleep mode? You should have drained the battery and turned it off then charge it.

I did drain it now - the sleep mode was last week, when I took some leave, and never worked on it. The battery health was OK the week before, and changed when I fired it up after the week's 'sleep'...

The recalibration has the Health up to 77%, but the status hasn't changed - which probably means that I will need to look at replacing it sooner than what I would have.

That being said - but I mostly use it as a desktop between office and home - so if I lose a bit on capacity between charges, I will live... Just annoying that the battery was a bit soft from day 1.

If it has a removable battery cant you take it out and run it via AC only?
